Just installed the Jb4 Stage two. Unfortunetly i did not have the right connections for the 4 wires im guessing. Although according to that link you can just set the 4 wires aside. Which i did. Now reconnecting the battery and starting the car i receive a DRIVETRAIN MALFUNCTION CODE...

Any help?

yes i had the same thing happen to me. I don't have the CANBUS hook-up like the pictures shows. I also got the drivetrain malfunction and engine light. I contacted Terry and he told me i can only run stage 1. They sent me stage 1 but haven't installed it yet. My car is in the shop for scheduled brake service.
